A new ClearLinux image has been uploaded to the Azure storage account.
It is based off of the ClearLinux cloudguest image 31310 version, with
two extra bundles added to it.
First bundle is sysadmin-basic to include utility like netcat, and the
second bundle is iperf, adding the iperf binary to the image.
The image is 2G in size.

Azure virtual machines can have private IPs in the 172.16.x.x range,
causing some issues with the VFIO test. By using 172.17.x.x for this
test, we avoid IP conflicts.

We no longer build vubridge, so we end up cloning qemu and building

An integration test relying on the new vhost-user-net backend now
replaces the previous test using the QEMU test backend. This allows
us to avoid building the QEMU backend, and we now really exercise the
vhost-user-net implementation as it is used for the ssh communication
in this test.

Rely on the newly generated Clear Linux image for the integration
testing of cloud-hypervisor. The image has been generated using the
Clear Linux clr-installer tooling, which means it is in compliance with
the Clear Linux licensing.
This new image contains one more bundle that was not part of the default
cloudguest image. This bundle is basic-sysadmin, and contains both nc
and socat utilities.

Running the integration test script showed the following error:

scripts/run_integration_tests.sh: line 84: [: missing `]'
+ -f /home/rob/workloads/vubridge ']'

This was preventing the test from reusing build QEMU artifacts.

The virtiofsd daemon takes a bit of time creating and listening on the
socket. By adding 10s timeout, we make sure the vhost-user socket has
been properly created before the VMM tries to connect to it.
Also, the daemon needs cap_dac_override capabilities to access debugfs
filesystem.
Last thing, both virtio-fs and virtio-pmem tests were slightly different
from the others since they were not explicitly killing cloud-hypervisor
and virtiofsd processes once the test was done.

In order to be able to use the latest version from virtiofsd binary, the
integration tests will now build it directly from a branch located on
sboeuf's QEMU fork. The same way the kernel is hosted on sboeuf's linux
kernel fork, this allows to update the version of the virtiofs daemon
based on latest patches from virtio-fs maintainers.

The last kernel we were using included some manual porting of the
virtio-pmem and virtio-fs patches. By moving to 5.3-rc3, we are now
closer to upstream since the virtio-pmem patches are part of the linux
kernel now. Additionally, this includes the latest patches from
virtio-fs maintainers, which works with the latest version of virtiofsd.

The VFIO integration test first boots a QEMU guest and then assigns the
QEMU virtio-pci networking device into a nested cloud-hypervisor guest.
We then check that we can ssh into the nested guest and verify that it's
running with the right kernel command line.

Add 2 integration tests to validate virtio-pmem works as expected.
One test takes care of checking the ability to read and write to this
persistent memory from the guest, and validates that the data is
carried over the virtualization boundary.
The other test ensures the VM can be booted directly from an image
that would be passed through virtio-pmem.

Launch the test binary by command rather than using using the vmm layer.
This makes it easier to manage the running VM as you can explicitly kill
it.
Also switch to using credibility for the tests which catches assertions
and continues with subsequent commands and reports the issues at the
end. This means it is possible to cleanup even on failed test runs.
